MANUFACTURE OF PERFORATED WRAPPING OR TOILET PAPER.

SPECIFICATION forming part of Letters Patent No. 390,328, dated October 2, 1888.

' Application filed September 2,1886. Serial No. 212.4691. (No specimens.)

To aZZ whom it may concern:

Be it known that I, SETH WHEELER, a citizen of theUnited States, and a resident of the city of Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in the Manufacture of Perforated Wrapping and Toilet Paper, of which the following is a specification, reference being bad to the accompanying drawings, forming part thereof.

This invention relates to the method of manufacturing perforated paper. With certain forms of perforations insuring quick and certain separation on a given line it has been found that the paper is liable to frequent breakage whether in flat or roll form. In other words, the paper is liable to separate, by reason of the character of the perforations, in process of manufacture before it arrives at the final form for use. By my invention this is entirely avoided.

It consists in making the perforations in definite limited lines and leaving unperforated at the ends of these lines portions of the paper, thus protecting and re-enforcing the lines of perforations by a longitudinal section or unperforated strip, which is detached from the roll after the roll has been taken off the machine or before binding for use in flat or sheet form for books. It is also generally applicable to all kinds of perforated rolled paper in that with this solid strip the rolls can be tightly wound and afterward the solid section or strip removed, thus preventing the liability of the paper being separated at the perforations during the process of winding, as is the case where the strip is not made use of.

In the drawings, Figure 1 represents one roll of a series of perforated rolls containing these unperforated strips, showing the unperforated strip not yet detached from the roll. Fig. 2 is a portion of a sheet, showing the unperforated strips removed. Fig. 3 is a modification showing a solid roll of unperforated paper between each two rolls of perforated paper, by means of which the same end is attained without any wastage.

a is the roll of perforated paper.

12 b, &c., are the definite limited lines of perforations made therein in the usual way of punching with a series of punches.

c c are unperforated strips, which are left unpunched by reason of the punches of the machine terminating a little short of the edge of the sheet, and there being provided in the machine knives which slit the paper in order to remove such strips. Thus across the machine there may be an unperforated strip between the contiguous ends of each roll, or simply marginal unperforated strips on the parent sheet, and in separating the rolls from each other after they have been perforated and out each roll will be in the condition shown in Fig. 1, thus preserving the roll in a shapely condition while it is being wound up.

In the modification, Fig. 3, a a show the ends of a series of perforated rolls of paper, I) I) being the perforations. In this case the perforated rolls are separated by a solid roll, which is seen at c c. This accomplishes the same object, the winding strain coming upon the plain strips 0 c, enabling the rolls to be solidly wound in a shapely manner-that is, without the ends bulging-and also prevent the perforations from being torn during the winding operation. The strips 0 c, &c., become solid rolls of unperforated paper in this instance.

This invention is also applicable to perforated sheets of paper manufactured in the flat, so as to be used for check, draft, and other books of like character containing detachable leaves.

1. The improvementin the art of manufacturing perforated paper rolls or perforated sheets in the flat, consisting in making definite perforated lines, as described, and leaving at the ends of these lines unperforated portions of the paper, forming continuous strips to support the tension and strain of winding or handling, and, finally, after the latter manipulation, removing the imperforate portions of the paper, substantially as described.

2. The improvement in the art of manufacturing perforated paper rolls, consisting in transversely perforating longitudinal sections of a continuous Web and leaving intermediate to support the tension of rewinding the same, 10 imperforate longitudinal sections of the web and, finally, after such rewinding, separating to support the tension of rewinding the same, the perforated and imperforate sections into substantially as described. independent rolls, substantially as described.
